Description of the conditions under which this exception is thrown

A new data store must be added to the partitioned region for future bucket creation.

When a PartitionedRegionStorageException message contains
the string:

Too many data store members have refused the request to create a bucket.

There are enough data stores, however some have refused possibly due to these
conditions:

The amount of storage allocated to the partitioned region on that
distributed member exceeds its localMaxMemory setting.

The partitioned region instance on that distributed member has been
closed or destroyed.

The cache on that distributed member has been closed.

The distributed system on that member has been disconnected.

When a PartitionedRegionStorageException message contains
the string:

Creation of a bucket for partitioned region failed in N attempts.

If the number of attempts is lesser than the number of available
data store members, contact GemFire support providing all logs and statistics files from
all members containing the partitioned region. Otherwise, shutdown and then restart one
or more of the data stores, given that it is safe to do so, for example when redundantCopies
is greater than 0.
